Answer:
2
Step-by-step explanation:
Basically you don't need to find x to know the scale factor ,
but I did.So you see that multiple 3 by 2 you will get 6
(MN) and the same will happen with 5.5 and NO (which is 11 btw).
so you can write 2:1
Answer:
1:21
Step-by-step explanation:
Easiest trick way to do this is do 26/546 on your calculator (if you got a scientific one) this would simplify this to its lowest fraction which can be converted into a ratio in this case the ratio of teachers to students is 1:21
I would approach the problem like this:
1 oz bottle.............................30cm^3
33 oz bottle.............................xcm^3
in a 33 oz bottle will be x=33*30=990cm^3
density=mm/v
13.6g/cm^3= m/ 990cm^3
m= 13.6 * 990=13464 g
or 13.464 kg in a 33 oz bottle
